SMMV: Secure multimedia delivery in vehicles using roadside infrastructure

Vehicular ad-hoc networks (VANETs) have gain a lot attention from academic and industry in recent years. It is seen as the most promising field to change the automotive industry, specially regarding road safety. The primary objective of this paper is to build an Android-based application that utilizes WiMAX IEEE 802.16 network protocols to send a multimedia message securely from one vehicle to another vehicle using infrastructure like rode side units (RSUs) or base station etc. The proposed protocol combines both AES encryption and SHA-256 hashing algorithms to secure the message. Thus, it enables the vehicle's driver to send multimedia messages securely to other drivers using voice commands without having to reach for a cell phone. We compared our proposed scheme in various car density environments such as urban and high-way scenarios. We justified our proposed scheme with simulation results in the end.
